Inspired by jazz guitarist Ron Eschete, the 91 was the first "floating" pickup to give archtop players the benefits of a low-impedance pickup. Using Alnico magnets and a specially designed internal preamp, the 91 produces a naturally warm, present tone reminiscent of some of the older floating pickups. This pickup is remarkably thin and will fit comfortably at the end of the fingerboard without interfering with string or top vibrations.
